CHARLES FRANCIS GETLER, OF MATTEAWAN, NEW YORK.

VENTILATOB FOB HATS.

Application filed July 6, 1914.

T0 aZZ 107101222? m ay concern Be it known that I, CHARLES FRANCIS GETLER, a citizen of the United States, residing at Matteawan, county of Dutchess, State of New York, have invented certain new and useful Improvements in Ventilators for Hats, of which the following is a specilication.

My invention consists in a device adapted to be placed within the brim of a hat, which is adjustable for any size of hat, and which will permit a circulation of air from without into th cavity and out of the hat.

The accompanying drawings will serve to illustrate my invention, in which similar numerals of reference indicate like parts.

Figure l is a vertical section through a hat showing the ventilating device in elevation and section. Fig. 2 is a reverse plan view. Fig. 3 is a vertical section through a portion of a hat and the ventilator. Fig. at is a front elevation of the ventilator with the ends detached. Fig. 5 is a similar view with the ends connected. F ig. 6 is a top view corresponding to Fig. 5. Fig. 7 is a section through the ventilator, showing the two ends of the regulating strip unconnected. Fig. 8 is a section through the ventilator, showing both ends of the regulating strip connected and secured.

In the drawings; 5 indicates a hat; 6, sweatband; 7, ventilator. The ventilator 7 consists of a flexible strip of metal 8. Around this strip of metal is coiled a spring 9 which, when fully extended, is longer than the strip 8. One end of the spring 9 is rigidly connected to one end of the strip of metal 8 at 10, through a plate 11, also connected to said strip of metal, and provided with a slot 12, through which the other end of the strip is passed, and in which it may move. The other end of the spring 9 is connected to a plate 13 also provided with a slot 14 through which the end of the strip is passed and in which it may move. Located near one end of the strip of metal 8 are shaped slots 15, and fastened to the other end of the spring are projections 16 adapted to coact with the slots 15.

It will be understood that by carrying the one end of the strip over the other and introducing the projections 16 in one or the other of the slots 15, the size of the diameter of the strip can be altered to the size of the interior of the hat and at the same time the Specification of Letters Patent.

spring 9 will be lengthened or shortened, in accordance with the change of diameter, and through its resilient pressure, hold the projection 16 in the slot 15 and the strip 8 extended to the required size.

I wish it understood that I do not limit myself in any wise to the device shown for increasing or decreasing the diameter of the strip when the ends are joined, as very many modifications would naturally suggest themselves. I am aware that it has heretofore been suggested to use a coiled spring as a ventilator for hats, but no means were provided for increasing or decreasing the length of the spring, and consequently its diameter, when the ends were connected, or for supporting the convolution of the spring against displacement from the position in which it is located in the hat.

Having thus described my invention, I claim:

1. A ventilator for hats, comprising a strip of metal, a coiled spring surrounding the strip of metal, and means whereby the ends of the strip of metal may be adjustably connected to alter the diameter of the strip in accordance with the size of the hat in which the ventilator is to be used.

2. A ventilator for hats, comprising a fiat strip of metal, a spring wound helically around said strip and connected at one end to one end of said strip, a slotted plate located over the other end of the strip and having the other end of the spring connected thereto, and means for adjustably connecting the ends of the strip to alter the diameter of the strip in accordance with the size of the hat in which the Ventilator is to be used.

3. A ventilator for hats, comprising a fiat strip of metal having slots at one end and a projection adapted to coact with said slots at the other end to change the diameter of the strip, and a wire wound helically around said strip connected at one end to one end of the strip, a perforated plate located over the other end of the strip, and the other end of the wire connected to said strip.

4. A ventilator for hats, comprising a flat strip of metal, means whereby said strip of metal may be adjusted in size to correspond to the size of the hat in which the Ventilator is placed, a wire wound helically around such strip normally longer than such strip and adapted to accommodate itself to the diameter of the strip when placed in a hat.

5. A ventilator i'orhats, comprising a flat a second slotted plate connected to the oppostrip of metal coiled in a circle and having site end of the coiled Wire. 7 the ends overlapping, a locking device for In testimony whereof, I aflix my signaadjustably determining the diameter of the ture, in the presence of two Witnesses. strip, a Wire Wound helically around said CHARLES FRANCIS GETLER. strip and normally longer than the strip, a Witnesses: slotted plate connected to one end of the HELEN E. KOLTSOH, strip and to one end of the OOllGdWiIG, and ETHEL M. GILLESPIE.
